But I'm pretty sure you *don't* use PTOptimizer, because the source code was
never published and opened. There are only 32bit binarys on the net.
http://article.gmane.org/gmane.comp.misc.ptx/4126/match=ptstitcher
But I have to use PTStitcher, because of it's few advantages over nona,
which I already use as 64bit stitcher in hugin.
advantages nona over PTStitcher:

advantages PTStitcher over nona:
http://article.gmane.org/gmane.comp.misc.ptx/2166/match=ptstitcher
http://article.gmane.org/gmane.comp.misc.ptx/3336/match=ptstitcher+ptoptimizer
I rely on especially on these advantages of PTStitcher as I have some panos
which are made out of some really bad shots (I didn't knew about the nodal
point, and therefore I have to morph them to fit).
- Automatic colour/brightness correction.
- Morph to fit.

I have the 64bit versions already from the ubuntu/breezy universe
repositories installed: 
$ apt-cache policy libpano12 libpano12-dev libpano12-bin libpano12 libpano
egrep -A1 "(lib|\*\*\*)"|egrep -v "(\-\-|status)"
libpano12:
  Installiert:2.7.0.10-1
 *** 2.7.0.10-1 0
        500 http://archive.ubuntu.com breezy/universe Packages
libpano12-dev:
  Installiert:2.7.0.10-1
 *** 2.7.0.10-1 0
        500 http://archive.ubuntu.com breezy/universe Packages
libpano12-bin:
  Installiert:2.7.0.10-1

Now I tried to use a script in hugin to use the 32bit chroot for PTStitcher,
but it doesn't works.

~/bin/PTStitcher
#!/bin/bash
dchroot -c i386_chroot -d PTStitcher $1 $2 $3 $4
exit

So, I'm not a good scripter and there might be a problem with $1 $2 $3
$4 ;-).

But anyway: I want to know how to link the 32bit png lib the right way, to
use PTStitcher and the other 32bit panotools from
http://www.path.unimelb.edu.au/~dersch/
http://www.path.unimelb.edu.au/~dersch/PanoTools.tar.gz
on my amd64 x86_64 breezy box.

kind regards
